This field records the proportion of the department in the academic cost centre.

Compulsory for institutions in England. Compulsory for all institutions in Wales, Scotland and Northern Ireland that choose to make a return. Not required for institutions in Wales, Scotland and Northern Ireland that choose not to make a return.

This field records the percentage of a department that maps to an academic cost centre, i.e. what percentage of a department maps to a particular cost centre.

Not all departments will map to one academic cost centre, and not all academic cost centres may feature staff from only one department.

For that reason, the data collected for each academic cost centre/department mapping includes:

• AcademicCostCentres.PROPACC: the proportion of the department present in a specified academic cost centre
• AcademicCostCentres.PROPDEPT: the proportion of a given academic cost centre which can be said to be attributable to a particular department.

AcademicCostCentres.PROPACC exists to identify instances where departments do not map into a single cost centre.

In the example below, there are two departments and two cost centres. The 'History' cost centre is composed only of staff from the Department of Ancient History. The 'Classics' cost centre, however, is made up of staff from the Department of Ancient History and also the Department of Classical Studies on a 5:10 basis:

• The Department of Ancient History to 'History' mapping has a PROPACC value of 50% - half of that department maps to the 'History' cost centre.
• The Department of Ancient History to 'Classics' mapping has a PROPACC value of 50% - half of that department maps to the 'Classics' cost centre.
• The Department of Classical Studies to 'Classics' mapping has a PROPACC value of 100% - all of that department maps to the 'Classics' cost centre.

The value in this field can be recorded to one decimal place and must be between 0 and 100. The length of this field is 5 characters, however data may be returned with or without leading zeros or the decimal place (e.g. 005.0 or 5.0 or 5).

For those institutions in Wales, Scotland and Northern Ireland wishing to make a return of academic department to cost centre mappings, the minimum requirement for such a return is that for each mapping, the fields AcademicCostCentres.ACCENTRE, AcademicCostCentres.DEPARTMENT, AcademicCostCentres.PROPACC and AcademicCostCentres.PROPDEPT must all be returned.

Further guidance regarding the calculating of proportions is available in the Further guidance on calculating proportions document.
